Both dramas beautifully depict how a woman (or women) takes revenge on men (their husbands) for different reasons. Both the shows uncover great revenge stories which are fun to watch for the audience.
Both the shows have a similar concept of a past connection between the male leads which leads them to being together in the present. They don't just have a past life connection, the leads are shown exploring this connection in detail. Both are heartwarming and cute rom-coms. :)
